64 bit FreeBSD for number crunching

[Michael Hopkins, Hopkins Research]

Hi

I am considering building a dual Opteron number-cruncher using FreeBSD 5.3
instead of Linux, and I have three questions which I haven't been able to
find answers to on the site.

1) Will I be able to link reliably against Linux libraries when the source
isn't available e.g. Some of those ones here...

http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_8796_11869%
5E11880,00.html

2) Is there any performance penalty to (1) if I can.

3) Is the 64 bit AMD port of FreeBSD stable?

Many thanks for your time

Michael
